2013 Alien Z with a Fury XT cam.
Shooting 56# on the -10 post, with a 29" draw.

I've been shooting this bow for a couple of months now.
Never shot anything so well in my life.
All dialed in with five months to practice till deer season.

One problem I need to get a handle on though.
That is the draw module seems to be damaging the cable serving.

I removed the module, dulled the sharp edge.
Removed the cable & reserved with BCY 2X, for good or bad it's all I have to work with.
Put everything back together & went to the range.

Last week, worked on setting the center shot by walk back tuning, then readjusted the sight housing.
Was worn out but happy the bow is back together.

Yesterday, got to spend three hours shooting.
X's and tiny groups (for me anyhow), best day at the target range EVER.
Except I can already see my serving is getting beat up, just two days of shooting later.

Is the problem likely the BCY 2X, my novice serving technique, or a bigger problem with cam, mod or limb?

I hope it's something simple because I really like this bow.

if its gettin chewed up about 3 or 4 inches up the cable the draw stop is set a hair to long and the cable actually comes in contact with axle and upon release the cam catches it and will eat your servin

Just checked to be sure.
The wear is in the center of the mod contact area.

Only enough that I can tell it does.

if u have already dulled the sharp edges it might just be your reserve job only way to tell would be to get a new cable

You could also polish the area that you've dulled, making sure that there are no tiny burrs present.

Shot yesterday after a range clean up party.
This thing shoots well.
Looks like I can get one more session before needing to reserve the cable for the second time.

Pulled the draw mod for the best inspection job I could manage.
Magnification, cotton ball (why not it works on limbs), & polishing paper.
I didn't find anything for certain.
With one possible exception.

The mod has a small groove machined in the face of where the cable rests at 1/4 to full draw.
I'm wondering if this groove is supposed to be there.
If it is an intentional part of the design, maybe it needs rethought.

The wife's Cougar FC mod looks identical. The grove might be a bit shallower.
Her serving is showing light wear at the same spot, after a year of shooting.
She shoots 34# at 25.5", I'm shooting 56# at 29.
It's likely the increased weight, draw length & amount I shoot has some effect on wear rate.

Any of you guys familiar with the Fury XT cam & draw mod?
Can someone get a look at one of the new production bows & check the mod for that grove?

Reserving every couple of weeks will get old fast.
Is there a significantly better choice than BCY X2 for serving the cable?

Think I found the problem.
A small area that is part of the bearing support is bent.
It probably got worse gradually as I used the bow.

Thanks for helping me think this through.
I'll contact CS & see about a replacement cam.

Called & left a message about 10:00 this morning.
Got a call back just before noon from John.

After discussing the situation John asked me to work through a dealer to receive replacement parts.
I explained no Martin dealer anywhere near me, that's why I bought through KM Archery Hut.
John said any archery dealer, doesn't have to be a Martin dealer.
Fortunately a member of my archery club fits the bill.

Timing & a little luck I should be back up and running in a couple of weeks.
In the mean time I'll have to be happy shooting my Scepter 4.
By the way, I was shooting my Z better than my X rigged Scepter. Figure that one out.

"New" Martin has some different rules than "Old" but, they are taking care of me and that's what matters.

Final update.

4-6 Talked to my club member / non-Martin dealer.
He agreed to handle the warranty exchange.

4-7 He spoke with John. John OK'd the shipment of my new cam.

4-11 Cam arrived in a padded envelope with no charges involved.

4-17 I was finally able to to get over and pick up the cam.
Less than an hour later it was on and firing arrows.

No tweaks or adjustments and I'm right back on target.

Maybe of interest is the finish of the new cam.
Overall better looking.
Machine work is much cleaner.
The anodize finish is smoother and the printing on the cam is sharper with better placement.

Two actual changes of note.
Lettering added alongside the draw stop slot. A through Z for draw stop position reference.
It's a bit busy, certainly better than previous which was nothing.
Different bearings.
The old cam bearings had a standing collar to properly fit the space between the limb tips.
The new bearings are flat faced and use included aluminum spacers.

The Z was down for a couple weeks as expected.
Most of the down time was on my end not Martin.
I'm back up and running like nothing ever happened.

My thanks to everyone involved in saving Martin from extinction & John for keeping CS issues painless.

Glad to hear they got you fixed up so fast. Looks like they might be showing some improvement in customer service again.

When I worked the Great American Sports Show I did take notice that the machining of all the cams seemed to be much improved from 2013. Can't exactly say about the finish on the bows. To me Camo is Camo so I'm never impressed by it. So long as it doesn't wear off or flake off it's doing it's job. Let's hope the job Martin has done with machining meets the expectations of the customers.

just out of curiosity, did they address your strings? aka, give you a new set?

I didn't ask for a new set.
I've reserved them & they are holding up fine now.
